Certain estimates of Antarctica’s total contribution to sea-level rise may be over, or even underestimated, after researchers detected a previously unknown source of ice loss variability. In a new paper published in The Cryosphere, researchers using Copernicus Sentinel-1 data, found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the first time that such seasonal cycles have been detected on land ice flowing into ice shelves in Antarctica.

The ESA Council at Ministerial level, CM22, is a time for critical decisions. In November 2022, ESA’s Member States, Associate States and Cooperating States will come together to strengthen Europe’s space sector and ensure it continues to serve European citizens.

NASA on Tuesday celebrated exceeding expectations during a mission to deflect a distant asteroid, in a sci-fi like test of humanity's ability to stop an incoming cosmic object from devastating life on Earth. The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around

Japan's space agency said it sent a self-destruct order to its Epsilon rocket after a failed launch on Wednesday because of a problem that meant the craft could not safely fly. The unmanned rocket, on its sixth mission, was taking satellites into orbit to demonstrate "innovative" technologies. "The rocket can't continue a safe flight, because of the danger it would create if it falls on

Emirati fleet operator Yahsat said Oct. 11 it has invested in Californian startup eSAT Global, which is developing a chip that would enable phones to connect to its satellites in geostationary orbit.

More satellite operators are considering providing services directly to standard mobile phones following early product launches, big-name announcements, and progress startups are making for their dedicated constellations.

NASA on Tuesday said it had succeeded in deflecting an asteroid in a historic test of humanity's ability to stop an incoming cosmic object from devastating life on Earth. The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around its big brother Didymos, said NASA c

Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft's kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale dem

Inmarsat Government won a 10-year contract valued at $980 million to provide broadband satellite and terrestrial communications services to the U.S. Navy.
